Scope of this technical record
Symptom-level gate-driver and power-stage decision route for EDS1000-2S0015 no-output cases.
This record does not authorize live repair. Isolate input power, verify DC-link discharge and use controlled bench procedures appropriate to hazardous industrial drive electronics.
No output requires power-path discipline
When the drive powers up but produces no usable motor output, the visible symptom sits at the intersection of external load, output semiconductors, isolated gate drive and control/protection signals. The EDS1000-2S0015 DB1 record gives a concrete map of that boundary: an H20R120 six-device output stage receives isolated commands through six A3140 drive channels.
This makes the model far more diagnosable than a generic low-cost inverter. A technician can document whether the failure belongs to motor/cable conditions, static power-stage damage, unequal gate-drive support or a controller/sensing path that prevents switching.
Driver-to-IGBT mapping
The six A3140 paths correspond to high- and low-side U, V and W switching positions. The drawing also exposes channel resistor and clamp networks that should be considered as comparable functional groups. A catastrophic IGBT event can damage only one channel yet make an apparently new output set fail immediately when the drive is energised.
A separate G7-related branch appears with the braking transistor/reference; it should not be confused with the six motor-output channels. Separating these two functions prevents a braking-path observation from being misread as a missing motor-phase driver.
No-output evidence routing
| Observation | First boundary | Do not assume |
|---|---|---|
| Motor/cable insulation suspect | External output path | Drive board is defective |
| Static bridge short evidence | IGBT/output stage | Only the motor caused trip |
| One driver channel differs | A3140/rail/gate network | New IGBTs are safe to fit |
| G7/braking anomaly only | Braking branch | All six motor gates are absent |
Repair decision
The database treats module replacement as the end of a proven diagnostic chain, not the beginning. If the six gate paths cannot be compared safely or the board is visibly damaged, stop repeated start attempts and prepare a board-level repair or replacement inquiry with photographs and component identifiers.
Field record checklist
- Capture exact model and board identifiers
- Record symptom timing and previous destructive events
- Preserve rail, connector and component evidence before substitution
Technical basis and reference documents
This is an independent editorial technical reference. Original manufacturer documentation remains controlling for installation, repair and commissioning decisions.
Establishes EDS1000 family identity, rating context and user-level fault/commissioning framework.
Board-level functional mapping derived from reviewed DB1 and DB2 circuit sheets; original drawing is not redistributed on the public site.
Confirms manufacturer/model identity, 1-phase 220 V / 7.5 A listing context, discontinued status and repair-channel presence.
